IMPROVEMENT IN BROOM-WINDING MACHINES.

Specification forming part of Letters Patent No. I ,048, dated May22,1877; application led October '27, 1876.

To all whom it may concern:

Be it known that I, JACOB GRAY, of Schenectady, 'in the county ofSchenectady and State of New York, have invented a new and usefulImprovement; in Broom-Winding or Broom-Making Machines, whichimprovement is fully set forth in the following specification, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figure 1 is an end elevation. Fig. 2 is asectional elevation of Fig. 1, showing the working parts and theirdifferent positions. Fig. 3 is a front elevation, and Fig. 4 is a plan.

Like letters and figures of reference indicate like parts in eachdrawing or figure, and the arrows the direction of motion.

My invention relates to that class of broomwinding machines in which thepower to operate the machine may be transmitted and broken at the willof the operator by a foottreadle and its connections, from any knownprime motor, such as steam, water, or horsepower, thereby giving theoperator the free'use of his hands to manipulate the brush and wire orcord in winding or making a broom.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

a a a a is a suitable and proper frame, constructed substantially asshown in the several drawings. H is a hollow barrel, wherein thebroom-handle is secured, and is provided with pulley A andfriction-wheel D, and is mounted in boxes on the forward part of theframe a, substantially as shown in Figs. 1, 3, and 4. F is a horizontalframe, pivoted at J and J, (see Figs. 2 and 4,) and having in its outerend boxes to receive and carry shaft 2, said shaft having thereonband-wheels A and B, and susceptible of an oscillating movement on thepivots J J. 3 3 (see Figs. 1 and 3) is a horizontal shaft, provided withpulley B and driving-pulley O, and placed in the lower back portion ofthe frame a, as shown, said shaft 3 having a steady motion through themedium of a belt (which is not shown) from the prime motor to the drivenpulley O. E (see Figs. 1, 2, 3, and 4) is a foot-treadle, supported uponthe fulcrum E, and the vertical stem E forms" the connection with theouter end of the treadle and the oscillating frame F, whereby the frameis moved up and down.

Xis a belt, which connects the pulleys A and A together, therebytransmitting motion from shaft 2 to the barrel H. X is a belt, wherebymotion is communicated from pulley B on shaft 3 to pulley B on shaft 2.D is a frictionpawl, engaging friction-wheel D on the barrel or hollowmandrel H.

The operation of my invention is as follows: Positive motion iscommunicated through a belt (not shown) to the pulley O on shaft 3,thereby giving to said shaft and pulley B a steady motion.

The normal position of the frame F, belts X and X, pulleys A and B,treadle E, and stem E, is as shown in Fig. 2 by the broken lines, belt Xnot engaging pulley B. The barrel H and all the moving parts of themachine, excepting shaft 3, are at rest.

The operator places a handle in proper position in the barrel H, andsecures it therein with the screw y. The wire or cord used to wind thebroom with is fastened to the end of the handle, as is usually done,(while the balance of the wire or cord is retained on a spool or drum,and the tension obtained by friction, which arrangements are so wellunderstood by those skilled in the art of broom-making that it isunnecessary to exhibit or describe the same.) The operator takes asuitable quantity of corn-brush and holds it in a proper position sothat the wire or cord can engage it against and around the handle. Hethen presses down with his foot the treadle E, which elevates the stem Eand frame F, thereby tightening the belt X on pulley B, which movementgives motion to the barrel H, carrying with it the handle and spinningon the wire or cord around the brush and handle. When sufficiently woundhe releases his foot from the treadle, which allows the frame F, by itsspecific gravity, to fall to its normal position, thereby releasing thetension of the belt X, and stopping instantly the barrel H. Thefriction-pawl D engages friction-wheel D on barrel or mandrel H, therebynot allowing it to revolve backward by the tension of the wire or cord.He then takes a sufficient with his foot for a brief period of time,gi.V.-

ing the barrel a partial revolution, thereby winding; on the shoulderjust placed. He then takes an equal quantity of brush for the oppositeshoulder, places it on the opposite side of the handle, and under thewire or cords, as above stated, depresses the treadle,

and winds on sufdcient wire or cord to hold the shoulders.

The shoulders are then out in proper form by the operator. He depressesthe treadle, and guides with his hand the wire or cord from off theshoulders onto thatportion of the handle where he spins on the hurl orfinal covering of the broom, which operation is performed substantiallyas above describedthat is, when the operator wishes to revolve thebarrel he depresses the treadle, thereby obtaining motion through thepants already described; and when he wishes to stop the barrel hereleases his foot from the treadle, thereby accomplishing the desiredresults.

This machineis almost noiseless, and cheap, simple, and durable in itsconstruction and operation, secures to the operator the full use of hishands to manipulate the corn-brush, wire, or cord, and relieves him ofthat labor which is necessary to work a broom-machine by hand, whilebrooms can be wound with great rapidity and ease.

What I claim, and desire to secure by Letters Patent, isv Thecombination of the barrel H, having thereon pulley A, with pulley A andbelt X, pulleys B and B, and belt X, oscillating frame F, treadle E, andstem E, substantially as and for the purposes shown and set forth. 7JACOB GRAY. Witnesses:
